Uncertainty(不确定度)一共有三种,分别是absolute uncertainty,fractional uncertainty和percentage uncertainty。 通常说uncertainty指的是absolute uncertainty。而fractional uncertainty和percentage uncertainty实际上是同种uncertainty的两种不同表示方法,只是fractional uncertainty最终结...
Absolute Optical Frequency Measurements with a Fractional Frequency Uncertainty at 1 10-15doi:10.1109/FREQ.2006.275430Jason StalnakerScott A DiddamsKihwan KimTara M Fortier
Relative uncertainty; Approximation error; Fractional error; and Percentage error. What is the relative error if I measured 42 and the true value is 40? The answer is 0.05 or 5%. To arrive at this result, we apply the relative error formula: relative error = |(actual - measured) / actual...
After the correction of systematic shifts, the clock transition frequency f_Ca+ = 411 042 129 776 393.2 (1.0) Hz is obtained, which corresponds to a fractional uncertainty within a factor of three of the Cs standard. Future improvements are expected to lead to an uncertainty surpassing the ...
allows us to determine the absolute frequency of the acetylene (ν1 + ν3) R(1)e transition at 6561.0941 cm−1with a fractional uncertainty as low as 6 × 10−12. By improving the previous record with buffer-gas-cooled molecules by one order of magnitude, our approach ...
